+# Phi-3 Mini SQL Generator — Merged Model
+
+Merged standalone version of [Shizu0n/phi3-mini-sql-generator](https://huggingface.co/Shizu0n/phi3-mini-sql-generator)
+— LoRA adapter weights fused into [Phi-3-mini-4k-instruct](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct).
+No PEFT dependency required for inference.
+
+## Evaluation — Base vs Fine-tuned
+
+Evaluated on 200 held-out examples from [b-mc2/sql-create-context](https://huggingface.co/datasets/b-mc2/sql-create-context).
+
+| Model | Exact Match |
+|---|---|
+| Phi-3-mini-4k-instruct (base) | 2.0% |
+| **This model (fine-tuned)** | **73.5%** |
+
+> Exact match: normalized SQL comparison (lowercase, strip whitespace/semicolons).
+
+## Why two versions?
+
+| Repo | Purpose |
+|---|---|
+| [`Shizu0n/phi3-mini-sql-generator`](https://huggingface.co/Shizu0n/phi3-mini-sql-generator) | QLoRA adapter — documents the training pipeline |
+| `Shizu0n/phi3-mini-sql-generator-merged` | Merged standalone — used for deployment and inference |
+
+## Training Details
+
+- **Dataset:** b-mc2/sql-create-context — 1,000 train / 200 validation examples
+- **Method:** QLoRA (4-bit NF4, LoRA rank 16, alpha 32, target modules: qkv_proj/o_proj/gate_up_proj/down_proj)
+- **Hardware:** NVIDIA T4 (Google Colab free tier)
+- **Training time:** ~21 min
+- **Final train loss:** 0.6526
+- **Best checkpoint:** step 250 (by eval loss)
+
+## Inference Example
+
+```python
+import torch
+from transformers import AutoModelForCausalLM, AutoTokenizer
+
+model_id = "Shizu0n/phi3-mini-sql-generator-merged"
+
+tokenizer = AutoTokenizer.from_pretrained(model_id, trust_remote_code=True)
+model = AutoModelForCausalLM.from_pretrained(
+    model_id,
+    torch_dtype=torch.float16,
+    device_map="auto",
+    trust_remote_code=False,
+    attn_implementation="eager",
+)
+model.eval()
+
+prompt = (
+    "Given the following SQL table, write a SQL query.\n\n"
+    "Table: employees (id, name, department, salary)\n\n"
+    "Question: What is the average salary per department?\n\nSQL:"
+)
+
+inputs = tokenizer(prompt, return_tensors="pt").to(model.device)
+with torch.inference_mode():
+    outputs = model.generate(
+        **inputs,
+        max_new_tokens=80,
+        do_sample=False,
+        use_cache=False,
+        repetition_penalty=1.1,
+        pad_token_id=tokenizer.eos_token_id,
+    )
+prompt_len = inputs["input_ids"].shape[-1]
+print(tokenizer.decode(outputs[0][prompt_len:], skip_special_tokens=True))
+```
+
+Expected output:
+```sql
+SELECT AVG(salary), department FROM employees GROUP BY department
+```
+
+## Validation
+
+Merge accepted after three smoke tests:
+1. PEFT adapter loaded on base model
+2. Local merged directory after `merge_and_unload()` + `save_pretrained()`
+3. Downloaded from this repo with `force_download=True`
+
+## Limitations
+
+- Fine-tuned on 1,000 examples — best suited for simple to medium complexity SELECT queries
+- Not tested on dialect-specific SQL (PostgreSQL/MySQL-specific functions)
+- May struggle with multi-table JOINs and nested subqueries

+    r"""
+    This is the configuration class to store the configuration of a [`Phi3Model`]. It is used to instantiate a Phi-3
+    model according to the specified arguments, defining the model architecture. Instantiating a configuration with the
+    defaults will yield a similar configuration to that of the
+    [microsoft/Phi-3-mini-4k-instruct](https://huggingface.co/microsoft/Phi-3-mini-4k-instruct).
+
+    Configuration objects inherit from [`PretrainedConfig`] and can be used to control the model outputs. Read the
+    documentation from [`PretrainedConfig`] for more information.
+
+    Args:
+        vocab_size (`int`, *optional*, defaults to 32064):
+            Vocabulary size of the Phi-3 model. Defines the number of different tokens that can be represented by the
+            `inputs_ids` passed when calling [`Phi3Model`].
+        hidden_size (`int`, *optional*, defaults to 3072):
+            Dimension of the hidden representations.
+        intermediate_size (`int`, *optional*, defaults to 8192):
+            Dimension of the MLP representations.
+        num_hidden_layers (`int`, *optional*, defaults to 32):
+            Number of hidden layers in the Transformer decoder.
+        num_attention_heads (`int`, *optional*, defaults to 32):
+            Number of attention heads for each attention layer in the Transformer decoder.
+        num_key_value_heads (`int`, *optional*):
+            This is the number of key_value heads that should be used to implement Grouped Query Attention. If
+            `num_key_value_heads=num_attention_heads`, the model will use Multi Head Attention (MHA), if
+            `num_key_value_heads=1 the model will use Multi Query Attention (MQA) otherwise GQA is used. When
+            converting a multi-head checkpoint to a GQA checkpoint, each group key and value head should be constructed
+            by meanpooling all the original heads within that group. For more details checkout [this
+            paper](https://arxiv.org/pdf/2305.13245.pdf). If it is not specified, will default to
+            `num_attention_heads`.
+        resid_pdrop (`float`, *optional*, defaults to 0.0):
+            Dropout probability for mlp outputs.
+        embd_pdrop (`int`, *optional*, defaults to 0.0):
+            The dropout ratio for the embeddings.
+        attention_dropout (`float`, *optional*, defaults to 0.0):
+            The dropout ratio after computing the attention scores.
+        hidden_act (`str` or `function`, *optional*, defaults to `"silu"`):
+            The non-linear activation function (function or string) in the decoder.
+        max_position_embeddings (`int`, *optional*, defaults to 4096):
+            The maximum sequence length that this model might ever be used with.
+        original_max_position_embeddings (`int`, *optional*, defaults to 4096):
+            The maximum sequence length that this model was trained with. This is used to determine the size of the
+            original RoPE embeddings when using long scaling.
+        initializer_range (`float`, *optional*, defaults to 0.02):
+            The standard deviation of the truncated_normal_initializer for initializing all weight matrices.
+        rms_norm_eps (`float`, *optional*, defaults to 1e-05):
+            The epsilon value used for the RMSNorm.
+        use_cache (`bool`, *optional*, defaults to `True`):
+            Whether or not the model should return the last key/values attentions (not used by all models). Only
+            relevant if `config.is_decoder=True`. Whether to tie weight embeddings or not.
+        tie_word_embeddings (`bool`, *optional*, defaults to `False`):

+            The base period of the RoPE embeddings.
+        rope_scaling (`dict`, *optional*):
+            The scaling strategy for the RoPE embeddings. If `None`, no scaling is applied. If a dictionary, it must
+            contain the following keys: `type`, `short_factor` and `long_factor`. The `type` must be `longrope` and 
+            the `short_factor` and `long_factor` must be lists of numbers with the same length as the hidden size 
+            divided by the number of attention heads divided by 2.
+        bos_token_id (`int`, *optional*, defaults to 1):
+            The id of the "beginning-of-sequence" token.
+        eos_token_id (`int`, *optional*, defaults to 32000):
+            The id of the "end-of-sequence" token.
+        pad_token_id (`int`, *optional*, defaults to 32000):
+            The id of the padding token.
+        sliding_window (`int`, *optional*):
+            Sliding window attention window size. If `None`, no sliding window is applied.
+
+    Example:
+
+    ```python
+    >>> from transformers import Phi3Model, Phi3Config
+
+    >>> # Initializing a Phi-3 style configuration
+    >>> configuration = Phi3Config.from_pretrained("microsoft/Phi-3-mini-4k-instruct")

+    >>> # Initializing a model from the configuration
